Sram GX1: The simple and affordable 1x mountain bike upgrade.
A few years back Sram came to the bike market with their XX1 drive train and all at once made 1x a seriously viable option for even the highest end bikes. By combining two important bits of tech they took 1x out of “kludge” territory into the mainstream. The only drawback at the time was price. Not only did Sram only introduce this tech at their top level of parts, but they also required a new hub standard and a proprietary crank jacking the price up further. A few years on, this has changed as the two key pieces of tech in the XX1 drivetrain system have trickled down to much more reasonably priced levels.
Our friend Fisher took advantage of this and chose to upgrade the old and worn triple/9 speed system on a nice used Cannondale mountain bike he picked up to the exact setup shown above.
For just $250 (including labor) he set up his bike with a narrow wide ring, clutch derailleur, 10 speed shifter, new chain, and new cassette. His bike is perfectly set up for the local trails, running smooth, and even a bit lighter.
For anyone interested in making this same upgrade, this same setup can be installed on just about any modern mountain bike.
Pretty neat.
